Scientists have developed a new machine learning approach that accurately predicted critical and difficult-to-compute properties of molten salts, materials with diverse nuclear energy applications. 

Stronger than steel and lighter than aluminum, carbon fiber is a staple in aerospace and high-performance vehicles — and now, scientists at Oak Ridge National Laboratory have found a way to make it even stronger. Using the Frontier supercomputer, they simulated 5 million atoms to study a novel process for making carbon fiber composites stronger and more cost efficient by incorporating a reinforced layer of polyacrylonitrile nanofibers, or PAN fibers. The research could lead to new ultra-durable materials for airplanes, electric vehicles, and a wide range of manufacturing applications that require stronger, more lightweight materials.

Using the now-decommissioned Summit supercomputer, researchers at the Department of Energy’s Oak Ridge National Laboratory ran the largest and most accurate molecular dynamics simulations yet of the interface between water and air during a chemical reaction. 

Researchers at the U.S. Department of Energy (DOE)’s Oak Ridge National Laboratory (ORNL) have developed an innovative new technique using carbon nanofibers to enhance binding in carbon fiber and other fiber-reinforced polymer composites – an advance likely to improve structural materials for automobiles, airplanes and other applications that require lightweight and strong materials. 

The Center for Bioenergy Innovation, or CBI, at the Department of Energy’s Oak Ridge National Laboratory has promoted Melissa Cregger and Carrie Eckert to serve as chief science officers, advancing the center’s mission of innovations for new domestic biofuels, chemicals and materials.

For astrophysicists, neutron stars stand out as objects of irresistible fascination — perhaps, in part, because of how difficult they are to decipher. But calculations conducted on the Frontier supercomputer, located at the Department of Energy’s Oak Ridge National Laboratory, have revealed new clues about the inner workings of neutron stars. 

Researchers at ORNL have developed a tool that gives builders a quick way to measure, correct and certify level foundations. FLAT, or the Flat and Level Analysis Tool, examines a 360-degree laser scan of a construction site using ORNL-developed segmentation algorithms and machine learning to locate uneven areas on a concrete slab. 

As the focus on energy resiliency and competitiveness increases, the development of advanced materials for next-generation, commercial fusion reactors is gaining attention. A recent paper examines a promising candidate for these reactors: ultra-high-temperature ceramics, or UHTCs.

Recent advancements at the U.S. Department of Energy’s Oak Ridge National Laboratory show that 3D-printed metal molds offer a faster, more cost-effective and flexible approach to producing large composite components for mass-produced vehicles than traditional tooling methods.

 

The research, conducted at the Manufacturing Demonstration Facility, or MDF, at ORNL, confirms that large-scale additive manufacturing is well-suited for creating complex metal molds, with efficiencies that could accelerate the adoption of lightweight composite materials in the automotive sector.

 

The fifth annual Quantum Science Center, or QSC, Summer School at Purdue University, held Apr. 21 through Apr. 25, 2025, welcomed its largest group of students to date. Experts from industry, academia and national laboratories gathered at the Purdue Quantum Science and Engineering Institute to share their research in multiple areas of quantum science.
